Direct answer
OAP Core Clinical childhood budgets are annual - unused funds do not carry over to the next fiscal year. Invoices must be submitted before the Ontario fiscal year end (March 31). Foundational Family Services are delivered directly by providers and do not involve a family-managed budget, so there is nothing to "expire" on the foundational side.
Every answer on this site sits on the same verified counts. These are the current figures.
Published:
The OAP operates on the Ontario government fiscal year: April 1 to March 31. Core clinical childhood budgets are allocated on an annual basis within this cycle. Any portion of the childhood budget not invoiced by March 31 is forfeited - unused funds do not roll into the following year.
Families and their OAP-approved providers should track service delivery and invoice submission throughout the year to avoid losing unspent budget. Providers are responsible for submitting claims; families should confirm that invoices are being submitted regularly rather than in a single year-end batch.
To maximize your OAP funding, work with your provider to plan services from the beginning of the fiscal year. Delays in starting services - such as provider transitions or assessment periods - can reduce the effective budget available for that year. Building a therapy schedule early in the fiscal year avoids end-of-year rush and lost funds.
Foundational services are delivered by regional service providers on a schedule set by MCCSS - families do not manage a Foundational budget and cannot "spend" or "lose" Foundational funding. These services continue regardless of fiscal year changes.
No. Unused OAP Core Clinical childhood budget funds are forfeited at the end of the fiscal year (March 31). They do not carry forward. Work with your provider to plan service use throughout the year.
The Ontario fiscal year ends March 31. All OAP core clinical invoices must be submitted before this date for that year's budget. Contact your provider to confirm invoicing timelines - many providers submit monthly.
Unsubmitted invoices after March 31 may not be payable from that year's budget. Contact the OAP at 1-833-425-2445 to understand your options if invoices were missed. Providers are contractually responsible for timely submission.

How long do families wait for Ontario autism services?
VerifiedOntario autism wait times for core clinical services now exceed 5+ years (Ontario Autism Coalition, July 2026). Funding invitations are currently reaching families who registered in August 2021 (Ontario Autism Coalition, July 2026 (reported from community intake)). This delay far exceeds the sensitive early intervention window recommended by developmental specialists.

Is the Ontario Autism Program underfunded?
VerifiedYes. The Financial Accountability Office (FAO) determined that $1.35 billion annually is needed to serve all registered children at 2018-19 service levels. The 2026-27 Ontario Budget allocated $965 million, leaving an estimated $385M+ annual shortfall. This gap is the primary driver of the perpetual 91,974+ child waitlist.
